Compare41F Hall Effect Sensor Details:
The SS41F is a small, versatile digital Hall-effect device operated by the magnetic field from a permanent magnet or an electromagnet and designed to respond to alternating North and South poles.
A built-in regulator provides enhanced stability of operation over 4.5 Vdc to 24 Vdc supply voltage range, and internal circuitry is designed to prevent sensor damage in case the supply voltage polarity is accidentally reversed.
The open-collector sinking output voltage is easily interfaced with various electronic circuits.
